Application filed January 14, 1905. Serial No. 240,983;

To all whom it may concern.-

Be it known that I, EDWIN M. Rosan- BLUTH, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Acetylene-Gas Apparatus, whereof the following is a specification, reference being had to the accompanying drawings.

My invention provides apparatus comprising a generator and a burner so constructed and arranged that it may be employed with particular advantage for surgical and other operations requiring a powerful light, which may be precisely located and directed.

As hereinafter described, my invention comprises a portable apparatus which may be readily separated and packed for transportation in a casing of relatively small dimensions, including a base arranged. to rest upon a floor and support a generator and a vertically-adjustable standard, which latter carries at its top a transversely-adjustable tubular arm, supporting at its end an adjustable burner-casing inclosing a reflector and burner and arranged to project the light from the latter in any desired direction.

It is characteristic of the generator hereinafter described that the carbid and carbidashes are both contained in a single receptacle constructed and arranged so that in one position water is permitted to gravitate to the carbid, the carbid is in contact with the moist ashes, and the gas is generated, where- :as in the inverted. position the carbid is not onl so held that the water is excluded from it, ut is separated from the moist ashes, so as to prevent its decomposition by the absorption of moisture from the latter, and the generation of gas ceases while the apparatus isv in this position. It is also characteristic of said generator that the contact of the carbid with the moist ashes and the separation of the carbid and ashes in the respective inverted positions described is effected by gravitation, the ashes being retained at one end in the carbid-receptacle and the interior of said receptacle being unobstructed to permit the traverse of the carbid from end to end thereof, toward or away from the ashes when the receptacle is inverted.

My. improvements comprise the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings, Figure I is a perspective view of an apparatus embodying my invention with the parts assembled for operation.

I Fig. II is a side elevation of the generator and its supporting-base. Fig. III is a vertical sectional view of the generator in the position shown in Fig. II. Fig. IV is a plan view of the casing-wall, through which water is introduced to the generator. Fig. V is a vertical sectional view of the burner-casing and parts connected therewith, as indicated in Fig. I. Fig. VI is a fragmentary vertical sectional view of a modified form of burnercasing.

As shown in Fig. I, the apparatus comprises the base 1, having three feet 2 resting upon the floor. Said base comprises the yoke 3, having bearings 5 upon its opposite sides to receive the trunnions 6 7 of the generatorcasing 8. Said yoke 3 is provided with the internal screw-threaded socket 10 at its top to receive the vertical tubular standard 11, which is detachably secured therein by its screw-threaded lower end, as indicated in Fig. II. The split collar 12 on said standard 11 is provided with the set-screw 14 to clamp the rod 15, which telescopes within said standard 11. Saidrod 15 is provided at its top with the bracket 16, having bearings 17 at its opposite ends, through which the rectangular tubular arm 18 is arranged to slide. Said arm 18 is provided at its end with. the socket 19 for the cylindrical shank 20 of the coupling 21, which may be set in any desired position of rotation by the j amnut 22. The upper end of said coupling is pivotally engaged by the clamp-screw 23 between the bifurcated lugs 24 of the bracket 25. Said bracket 25 is permanently connected with the casing 27, having the socket 29 for the removable handle 30, by which it may be turned in any direction, and said casing 27 is removably connected by the screws 32 with the casing 33 of the reflector 34. The burner-tube 36 is permanently secured in said. bracket 25 and provided at its forward end with the socket 37, in which the burner 38 is seated. I

The burner-casing 39 is provided with the chimney-vent 40 and is slotted, as indicated, at 41, so as to embrace said burner-socket 37 in removable engagement with the periphery of said reflector-casing 33.

The burner-casing 39 is provided with the guide-flange 42 at its front end and guidering 43, secured thereto by the straps 44 to receive removable diaphragms 45, having openings 46 of different sizes or a lens 47, as

in Fig. VI.

It is to be understood that the rod may be both vertically adjusted and rotated in the standard 11 and be clamped in any desired position by the set-screw 14 and that the arm 18 may be adjusted horizontally through the bearings 17 to any desired extent. Likewise the bracket-coupling 21 may be rotated to any desired angle in its socket 19 and be secured in adjusted position by the jam=nut 22. Said bracket 25, carrying the burner-casing 39, may also be tilted to any desired angle of inclination in a vertical plane on the horizontal screw 23 and be secured in its adjusted position by said screw, the gas being supplied to said burner 38 through the flexible conduit 48, extending from said tube 36 to the nozzle 50, extending from the side of the tubular arm 18. The opposite end of said arm 18 is provided with the nozzle 52, which is connected by the flexible conduit 53 with the nozzle 55, through which the gas is discharged from the generator-casing 8. As shown in Fig. 111, said nozzle 55 is carried by the removable cap 57, having a screwthread engaged with the screw-threaded flange 58 on the trunnion 7, and said cap car- 7 ries the filter-casing 60, in which is removable filtering material to separate entrained moisture from the gas. As indicated, said filtering material conveniently comprises a body of ashes 61 and absorbent-cotton partitions 62. Said trunnion 7 is rigidly con nected with the generator-casing 8 by the circular flange 65, and its inner end is secured to the casing 66, which separates the water-chamber 67 from the carbid-chamber 68, which latter is in communication with the gas-outlet 55 through the openings 69, leading tosaid trunnion 7.

The generator-casing 8 is conveniently made rectangular and provided upon opposite walls with annular screw-threaded flanges 71 and 72, having respective gaskets 73 and 74 and arranged to receive removable lids 76 and 77, provided with projecting bosses 78 and 79 or other means by which they may -be conveniently engaged and rotated to be removed and replaced.

As indicated in Figs. III and IV, the wall of the casing 8, to which the flange 71 is secured, consists of a metal plate 80, having a circular series of slots 81 opening into the water-chamber 67, so that when said lid 76 is removed with the casing in the vertical position shown in Fig. 111 said chamber 67 may be charged with water by pouring the latter upon said wall 80 within said flange 71, from which it gravitates to said chamber. Said wall 80 is provided with the central screwthreaded socket 83 for the bushing 84, which latter comprises the water-inlet passage 86, through which the reciprocatory plunger 87 extends. Said plunger is loosely mounted in said passage-way, so that it may be reciprocated to remove any ashes which may accidentally lodge therein and normally re stricts the flow of water to a thin tubular film around it.

The reversible receptacle which contains the carbid 87 and ashes 88 together and is arranged to bring them into contact or separate them in accordance with its position comprises the cylindrical shell 90, having removable lids 91 and 92 at its opposite ends and the foraminous diaphragm 93, forming the chamber 94, into which particles of ashes may be sifted when the generator is turned to the ino erative position shown in Fig. III, in whic po sition the carbid 89 is separated fromthe moist ashes 88, the latter being retained in the reccptacleadjacent to its lid 91.

As shown in Fig. 111, the receptacle-lid 91 comprises a thin sheet-metal plate having the central dome 96 in concentric relation with the plunger 87, and said dome is surrounded by channels 97, extending radially and circumferentially and adjacent perforations 98. Said channels open outwardly, so that they may be readily cleaned of any deposit of ashes when the receptacle is removed from the generator-casing, but are normally closed by the circular pad 99, of asbestos,

felt, or other porousmaterial, upon whichv said lid 91 of the receptacle rests when in operative position, such osition being of course the reverseof that s own in Fig. 111.

It is to be understood that in the operative position of the generator the water-inlet 86 is submerged, and the water subsiding in the water-chamber 67 and rising through said inlet percolates throughthe pad 99, channels 97, and perforations 98 to the carbid-ashes 88 and carbid 87, which are then in contact.

However, it is to be understood that the.

water cannot subside in the chamber 67 and rise through said passage 86 except when the vacuum-valve 100 is j:

gress of air to said cham er 67.

The gas generated within the receptacle upon admission of water, as described, escapes thence into the carbidchamber 68, surrounding said receptacle, and passes through the gas-outlets 69 to the hollow trunnions 7, wherein it is deprived of its entrained moisture by the filtering material 61 and 62 before its discharge through the nozzle 55 and conduits connected therewith to the burner 38.

The generator above described may be conveniently oscillated and inverted from operative to inoperative position by means of the handles 101, projecting from the trunnion 6, and said casing is conveniently stopped in either position by the pin 102, which projects inwardly from the yoke 3, as indicated in dotted lines in Fig. 11, in such position asv to be encountered by the opposite lugs 103 and 105, projecting from said burner 6.

I find it convenient to prevent the accidental displacement of the generator by the locko ened to permit ining-bolt 107, which is arranged to reciprocate in the boss 108 on the yoke 3, and is provided with the spring 109, which presses it into engagement With either of the recesses 110 and 111 in the collar 112 on the trunnion 6, which recesses respectively correspond with the inoperative and operative positions of the generator.

Although I find it convenient to support the arm 18 from the floor by a vertically-adjustable standard, as indicated in Fig. I, it is to be understood that said arm may be otherwise supported, for instance, by a bracket eX- tending from a vertical Wall.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as various modifications may be made therein without departing from the essential features of my invention.
